passenger anxiety

Hi, for some time now i have developed passenger anxiety. But the issue i only seem to get anxiety when i’m in the car with my father.

Last year my parents got into a bad car accident (my father was 100% at fault, but didn’t mean to and feels extremely guilty for it) it was bad to where we found out if the car hit them an inch more, my mom would no longer be here.

my dad drives carefully nowadays, but i fear that he will make the same mistake he made when the accident happen. i feel guilty for feeling afraid, but i just get very afraid. his turns are always very wide, which freaks me out more.

i have tried ways to distract myself, but no matter what, i cannot and the fear forces me to be alert whenever he’s driving.

so i’m just asking, what can i do to make sure im not all afraid. i feel guilty and upset about being afraid because i know that he genuinely did not mean for the accident to happen.

(I myself do not drive, as i have a few personal health reasons that block me from driving)
